On Sunday, the Palestinian National Authority sent eight firefighting trucks through the Gilboa Mountains to help Israel fight the massive fire in Haifa, which has consumed about 9,880 acres of land and prompted the evacuation of a quarter of the city’s population.

Overnight between Friday and Saturday, the Palestinians sent two other trucks from Ramallah to help put out a fire in the Jewish West Bank settlement of Halamish, Israeli officials said.

The fire has damaged at least 40 settlement homes and lightly injured four.

Greece, Cyprus, Russia, Croatia, Turkey and Italy have also sent crews and planes to assist Israel in its efforts to fight the fires.

On Saturday afternoon, a Boeing-747 Supertanker, the world’s largest firefighting plane, was put to work in an area between Jerusalem and Tel Aviv.

Experts said an unusually dry and windy weather condition has helped stoke the fires that broke out on Tuesday and spread across half of the country.
